                                throws ValidationException

      Create a validator for an empty content model
      Parameters:
        `type` - the empty content type
        `next` - the next receiver in the pipeline
      Throws:
        `ValidationException` - if the schema is incomplete or incorrect

  - ### Method Detail

    - #### getSchemaType

          public SchemaType getSchemaType()

      Get the schema type against which we are validating, if any
      Specified by:
        `getSchemaType` in class `ContentValidator`
      Returns:
        the schema type that this validator is validating against, or null

    - #### getChildValidator

          public ContentValidator getChildValidator()

      Description copied from class: `ContentValidator`
      Get a validator to handle the children of the current element. This is called immediately on return from the startElement call that starts this element.
      Specified by:
        `getChildValidator` in class `ContentValidator`
      Returns:
        the validator to be used to handle the children

    - #### startElement

          public void startElement(NodeName nameCode,
                          SchemaType typeCode,
                          int locationId,
                          int properties)
                            throws XPathException
